Once you begin driving, this system should display a visual of each of your Elantra’s tires along with the pressure reading for each one. If you have a tire with low pressure, an amber warning light will appear on your dashboard and your TPMS will indicate which tire needs more air.
It’s important to remember that while the TPMS is a handy built-in system, the most accurate way to check your tire pressure is by manually using a tire pressure gauge on each tire, especially before going on long drives.
Making sure your tire pressure is at the correct level isn’t just beneficial for safety reasons—it also reduces the amount of time it takes your car to brake, improves your gas mileage, and creates less wear and tear on your tires over time.
